Describes a simulated laboratory research project in which the thermodynamic and kinetic aspects of ammonia synthesis are simulated on a computer. (MLH)

Discusses teaching the concept of temperature at several levels of difficulty; includes ideal gas thermometers and the kinetic theory of gases. (MLH)

Describes an experiment that follows the progress of a chemical reaction with radiochemical tracer techniques, using the beta-emitting radioisotope iodine 131. (MLH)

Limitations of classical mechanics in understanding molecular properties are discussed. Modifications introduced by quantum mechanics enable the instructor to include and integrate important concepts from thermodynamics, quantum mechanics, spectroscopy, and statistics. (DF)

Discusses student use of the computer with mathematical models and with laboratory simulations. Examples given. (DS)

Students' cars and wristwatches are used as "apparatus" to introduce and demonstrate Newton's second law of motion. Forces acting on cars are discussed and typical student data (for different makes of cars) are provided. Data could also be used in discussions of work, horsepower, efficiency, and energy cost. (JN)

Provides an explanation for the observed motion of frisbees, can lids, "clay pidgeons," and flat stones when these objects are thrown through the air. Explanation focuses on forces (gravity and air), torque, and gyroscopic precession. (JN)
